The Calgary Tanks at Dieppe
Since 1942 the Dieppe Raid has been the subject of much controversy and debate concerning its political and military background, aims, plans, execution and supposed “lessons learned.” Although historians have documented their arguments well, they have not examined accurately or in any detail the operations of The Calgary Regiment (Tank), 14 Canadian Army Tank Regiment (14 CATR), Canadian Armoured Corps. Some misunderstandings and myths concerning the tanks and men, their performance and conditions affecting their actions, must be dispelled. At this point it is worth noting that not only was 14 CATR the first Canadian armoured unit ever to go into action, it was the first time in history tanks were used in an amphibious landing, as well as the baptism of fire for the latest British equipment, such as the Tank Landing Craft (TLC), the new Churchill tank and its 6-pounder gun

The free energies of formation of aqueous d-alanine, l-aspartic acid, and d-glutamic acid
The employment of thermodynamics in biochemistry has been restricted, until recently, to the use of first law data. In the last few years a beginning has been made in the application of the second law; i.e., of free energy data (1, 2). The development of this field is limited by the paucity of available free energy data. We have therefore undertaken the systematic determination of the free energies of formation of compounds which may be interesting in biochemistry or physiology
EPA’S STAGE 2 DISINFECTION BYPRODUCTS RULES (DBPR) AND NORTHERN KENTUCKY WATER: AN ECONOMIC AND SCIENTIFIC REVIEW
Implementation of EPA’s Stage 2 Disinfection Byproducts Rules (DBPR) in Northern Kentucky will cause a water rate increase of over 25%. Hence a review was undertaken, considering both economics and science in the context of President Obama’s 2009 scientific integrity directive. The rules purport to avoid up to 0.49% of new bladder cancers by reducing the levels of DBPs in drinking water – a benefit so small that failure to implement will not cause unreasonable risk to health (URTH). It suggests at most one Northern Kentucky death avoided over 17 years for a cost of 1700 per household). Even this small benefit is probably overstated. EPA finds no “causal link” between DBPs and bladder cancer, and EPA acknowledges problems with the epidemiological data used in their calculation: the data appear contradictory and inconsistent, may be skewed toward “positive” results, and suggest different cancer sites than animal studies. Two similar inter- national agencies disagree with EPA’s conclusions. The science is based on the Linear No Threshold (LNT) dose response model for DBPs, but this may not be the correct model. 83% of EPA’s epidemiological data show a statistical possibility that low levels of DBPs might be beneficial or have no effect
THE PRIVY COUNCIL OFFICE INTELLIGENCE ANALYST COMMUNITY OF PRACTICE: MISSION, VISION, ROLE, AND PRIORITIES
On November 17, 2023, Dr. Hugh Henry presented The Privy Council Office Intelligence Analyst Community of Practice: Mission, Vision, Role and Priorities for this year’s West Coast Security Conference. The presentation was followed by a question-and-answer period with questions from the audience and CASIS Vancouver executives. The key points discussed were the composition and goals of the Intelligence Analyst Community of Practice (IACOP); the four pillars of IACOP: training and tradecraft, excellence, human resources and career development, and equity, diversity and inclusion; and the next steps of IACOP to address these pillars through the development and implementation of programs and initiatives.

The preparation of crystalline lactic acid
On account of its importance in intermediary metabolism, lactic acid was among the first compounds chosen in our plan, which we have described in a previous communication (1), to augment the available data on the free energies of formation of substances significant in biological chemistry. It was necessary for this purpose to obtain pure crystalline lactic acid, free of water, anhydride, and lactide. The only description in the literature of the preparation of crystalline lactic acid is that of Krafft and Dÿes (2). Table I shows that the product obtained by their method contains relatively large quantities of anhydro impurities. The subject of the present communication is the description of a method which yields the active isomers of lactic acid in a crystalline state, free of water, anhydride, and lactide, supplemented by the description of two methods of separating the active forms from the commercial syrup (1). Lactic acid commercially available at present either is in the form of the U.S.P. syrup, which usually exhibits a low optical activity corresponding to the excess it happens to contain, which is variable, of one or the other optical isomer, or is the expensive zinc sarcolactate. The methods described below now make it possible to obtain easily and quickly and at low cost large quantities of both active isomers in a relatively high degree of purity
Non-Hostile Casualties in These Kinds of Wars from the Korean War to Operation Iraqi Freedom
This thesis provides a detailed study of the non-hostile deaths of the Korean War, the Vietnam War, Operation Desert Storm, and Operation Iraqi Freedom. This document examines the causes of the non-hostile deaths, from illnesses, accidents, friendly fire, and other injuries, as well as the trends in each war and the impact that these casualties exerted at the time they happened. In addition, this thesis explores the lessons the Armed Forces leaders applied between the wars in an effort to reduce non-hostile losses for the next war
Stratigraphy and correlation of Precambrian volcanic rocks, Eminence, Missouri
A portion of the Precambrian rocks located in the vicinity of Eminence, Missouri are studied and describes. These rocks are exposed as rhyolitic knobs protruding through hills of Ordovician sediments. The Precambrian rocks under study consist principally of rhyolite, with smaller amounts of tuff and creccis. The rhyolite is a potash rhyolite porphyry, both flow banded and unbanded, with phenocrysts of kaolinized orthoclase in a matrix of quartz and orthoclase. The tuffs contain devitrified glass shards and occasional ash balls such as those exhibited at Cott Mountain. A stratigraphic sequence was determined with the oldest rocks to the south at Stiegel Mountain and the younger rocks at Coot Mountain to the north. The tuffs occur between rhyolite flows. The entire sequence has a general dip to the north; but local variations in dip and strike occur. Basal conglomerate formed from rhyolite boulders occurs with the Ordovician sediments, particularly at the Little Rocky Creek Ford knob. The possibility that the Eminence rhyolites are ignimbrites was studied and rejected --Abstract, Page ii

The planning, intelligence, execution and aftermath of the Dieppe raid, 19 August 1942
On 19 August 1942 a mixed Anglo-Canadian amphibious force raided the German occupied port of Dieppe in Normandy, France, resulting in probably the worst disaster in Canadian military history. The operation, code-named Jubilee, lasted just nine hours and resulted in more casualties, proportionate to the forces involved, than in any other Western Allied operation of the war. As with any military failure, immediate myths and misconceptions arose that have simmered to boiling point many times during the last fifty years,Please be aware that the text in the supplied thesis pdf file may not be as clear as text in a thesis that was born digital or digitised directly from paper, due to the conversion in format. However, all of the theses in Apollo that were digitised from microfilm are readable and have been processed by optical character recognition (OCR) technology which means the reader can search and find text within the document
